US to Keep Military Pressure on IS

US to Keep Military Pressure on ISUS to Keep Military Pressure on IS

US President Barack Obama vowed at the United Nations on Wednesday to keep up the military pressure on IS militants and urged those who have joined the extremist group in Iraq and Syria to "leave the battlefield while they can."

Before he spoke, US-led airstrikes for the third time this week pounded Islamic State targets in Syria and Iraq.

"The only language understood by killers like this is the language of force," he said in his speech, which ran to just under 40 minutes.

Obama used his annual address to the 193-nation General Assembly to send messages to Russia to "changes course" on Ukraine, for Iran to "not let this opportunity pass" to forge a nuclear deal and, indirectly, for China to resolve its disputes with its Asia-Pacific neighbors.
